Abstract: 920,084. Fluid-pressure servomotor-control systems. SULZER FRERES S.A. March 11, 1959 [March 12, 1958 (2)], No. 8425/59. Class 135. In a process control system a common desired value setting unit is associated with at least two regulators having different modes of response and a transducer or transducers is or are located between the regulators and the setting unit to compensate for the different modes of response. A through flow steam generator, Fig. 1, comprises a pump 1, an economizer 3, super-heaters 5 and 6 and a burner 9 having air and fuel conduits 10 and 11, respectively. There are five control loops A, A<SP>1</SP>, B, C and D. The control loops A, A<SP>1</SP> are coupled and comprise the temperature detector 15, the first comparison unit 32 which receives a signal from the detector 15 and a desired value signal from the transducer 27, a second comparison unit 43 which receives a measured value signal from a flow meter 7 and a desired value signal from a transducer 22. The signals from the comparison units 32 and 43 are combined in a unit 31 which transmits a signal to the unit 30 which actuates the valve 2. The control loop B comprises a comparison unit 44 which receives a measured value signal from a temperature detector 37 and a desired value signal from a transducer 26 and transmits a signal to the unit 33 which actuates a water injector valve 35. The control loop C is similar to loop B and comprises detector 40, comparison unit 36 and valve 39. The control loop D comprises comparison units 41, 42, each of which receive a measured value signal from a pressure detector P and a desired value signal from transducers 23, 24, respectively. The comparison units 41, 42 transmit signals to units 45, 46, respectively, which units also receive signals from the comparison unit 32 of the control loop A. The signals from the units 45, 46 are respectively transmitted to fuel and air control valves 14, 13. The transducers 22-27 are connected to a common set point mechanism 20 comprising a shaft 60 actuated by a hand wheel 21 and having cams 61 forming the input members of the transducers. Each transducer receives a mechanical input signal and gives a mechanical, electrical or hydraulic output signal with delay, proportional, derivative and integral characteristics as desired. In another embodiment, Fig. 3, the furnace 101 of a steam generator has a burner 102 having a fuel supply line 103 and an air supply line 104. The fuel is pulverized coal and is delivered by a conveyer 106 driven by a motor 108, the speed of which is controlled by a regulator 109. The air supply from a constant-speed fan is controlled by a throttle valve 110 the motor 116 of which is controlled by a regulator 111. The line 112 is connected to a common desired value setting unit and a transducer 115 introduces a delay into the signal to the regulator 111 to compensate for the different modes of response of the regulators 109, 111.

Title: Improvements in or relating to processes for making shaped carbon bodies and the shaped carbon bodies resulting from said processes
IPC: C04B35/52
Filed: 1949-03-29
Abstract: Shaped carbon bodies, e.g., electrodes, arc lamp carbons, brushes, bricks, blocks, tubes, bearing rings and plates, are made by mixing raw uncalcined coke, obtained by carbonizing liquefiable hydrocarbons and having a volatile content exclusive of water of 8-20 per cent, with a plasticizer which is substantially convertible to carbon on baking and is not thermally decomposable or substantially vapourizable below 500 DEG F. heating the mixture to 100 DEG -400 DEG F. to form a uniform plastic mass, forming the mass into shape by pressure, and baking with gradual heating to 1000 DEG -2000 DEG F. to carbonize the decomposable matter and reduce the volatile content, suitable coke is obtained by thermal cracking or coking of petroleum hydrocarbon oils, cracked asphalts, straight run asphalts, coal tar pitch, or wood tar pitch. Plasticizers are cycloparaffins, coal tar oils and pitches, anthracene oil, lignite, tar oils and pitches, wood tar oils and pitches, asphalt, phenanthrene, diphenyl, anthracene, or chloro-, hydroxy-, methoxy-, amino-, or nitro-substituted compounds such as nitrobenzene, m-dinitrobenzene, o-nitrophenol, o-cyclohexylphenol, o-nitroanisol, o-nitroaniline, o- and m-nitrochlorobenzene, 2 : 4 dinitrochlorobenzene, mono-and di-nitrotoluene, mono- and di-nitroxylenes, o-nitrodiphenyl, or a -nitronaphthalene, or mixtures of these; 10-40 per cent by weight is usual and the aromatic plasticizers are preferred.  Raw petroleum coke say 4-20 mesh is mixed with the plasticizer under non-oxidising conditions in the cold, or at 100 DEG -200 DEG F. if necessary, and the mixture heated to 300 DEG F. for 30 minutes with continued mixing before being extruded, moulded, or cast.  The shaped bodies are baked by heating at a temperature increasing by 5 DEG F. per hour to 1740 DEG F. for 12-20 days and may be subsequently graphitized at 4000-5070 DEG F.

Abstract: 854,366. Measurement of dielectric loss. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. March 19, 1957 [March 19, 1956], No. 8522/56. Class 37 In apparatus for measuring the energy dissipated in a circuit element e.g. as shown, an insulating specimen 10, the latter is connected in series with an A.C. supply from transformer 16, one of three capacitors 20a..c and one of three resistors 24a..c, the power being measured by a wattmeter having fixed and moving coils 42, 46 included in the negative feed-back circuits of their supply amplifiers 32, 36 respectively. The voltage across the specimen is applied to coil 42 and, first, the voltage across the capacitor and then, by switching switch 18, that across the resistor, is applied to coil 46, the two wattmeter readings each being proportional to the scalar product of the appropriate voltages and their ratio to the tangent of the loss angle #, provided the wattmeter has been calibrated correctly. In setting up the apparatus, the voltage (I/w# sin wt) across capacitor 20b is applied to amplifier 36 through cathode follower 34, the reading on meter 52 being noted, the switch 18 being then set so that the voltage across resistor 24b (IR cos wt) is applied to amplifier 36 the resistor being adjusted until the meter reading is the. same as before i.e. RwC is unity. Switch 18 is now set so that the first wattmeter reading referred to above i.e. when the voltage across the capacitor is connected to coil 46 can be made and the gain of one or both of the amplifiers adjusted until the wattmeter shows full scale deflection. The mean values of the scalar products of voltages to which the readings are proportional are stated to be V1 - cos # and VIR sin # their ratio being RwC WC tan # and since RwC has been made unity the ratio represents tan # directly. An ammeter can replace voltmeter 52 or a meter can be connected to the appropriate amplifier output. Alternatively, the output of cathode follower 34 can be connected to the input circuits of both amplifiers 32, 36 and the resistor 24b adjusted until there is no change in wattmeter deflection when resistor 24b and capacitor 20b are interchanged. The cathode follower units 28, 34 and amplifiers 32, 36 are of conventional design (circuit diagrams Fig. 2, not shown).
